AMD Phenom x4 9550 only 1 core working

post #1 of 6
Thread Starter 
I have a AMD Phenom x4 9550 and running Xp.
Problem is it showing only 1 core is running via CPU-Z, task manager, OCCT, etc.
When it boots up CPU is identified correctly and 4 core.
Any suggestions to trouble shoot whether the problem is the CPU, mobo, or OS?
Don't have another CPU or mobo.

have you been messing with msconfig lately?

No the system got a virus and after wiping and reinstalling fresh XP install I noticed the 1 core issue. It's my mother in laws so she didn't mention any core prob because she knows nuthin about such things.
But this is a fresh clean install.
Did check the "msconfig" to check cores options and it only showes 1 that can be chosen, so no changes made. Also mobo has latest bios.
i have run occt memtest and it gives 10394 errors on a 19 pass test, related unsure.

sounds hardaware related. Try reseating your CPU.

To start off I wanna thank you fellas for trying to help me.
she does alot of stuff on ebay and was getting very impatient so tonight it went back to her as is.
I also found that the psu was only supplying just a lil under 5v on the 12 rail. I think it has multiple problems but she was losing it and taking every one around with her, lol.
In the next few weeks she is gonna have me get her a new psu, and some fans for a new case I got her and I'm gonna do the upgrades I been trying to get her to let me do for 6 months
They include new psu, new cpu (it is covered by warranty) and upgrading to win 7 (which she has in a box for 5 months). I also got rid of a OLD 40 gb hdd she was running her OS on and replaced it with a 300gb with larger cache, and a 1 terabyte for backup both SATA.

So for now I just hope it holds together till I get it upgraded, but this time I will have a loaner on stand by,lol
thanks again for the help and reply's.
